Hitting the century mark in an understudied, hyper-diverse lineage: Transcriptome-based phylogenomic analyses across the diatoms (Bacillariophyta).

Diatoms (Bacillariophyta) are a highly diverse and understudied lineage of photosynthetic microorganisms, and feature surprising metabolic pathways, prevalent cross-kingdom horizontal gene transfer, and wide morphological diversity. Understanding the evolution of these and other features throughout the Bacillariophyta, however, requires well-supported phylogenetic hypotheses, which to date have remained elusive. To this end, we have sequenced the transcriptomes from over 100 diverse diatom species, and report here on our efforts to identify orthologous clusters of single- and multiple-copy genes and further utilize these markers in supermatrix- and supertree-based phylogenetic strategies.
